Variables | |
msg_hclass_t | sip_unsupported_class [] |
Header class for Unsupported header. | |
tag_typedef_t | siptag_unsupported |
Tag for Unsupported header object. | |
tag_typedef_t | siptag_unsupported_str |
Tag for string with Unsupported header value. | |
#define SIP_UNSUPPORTED_INIT | ( | ) |
Initializer for structure sip_unsupported_t.
A static sip_unsupported_t structure for Unsupported header must be initialized with the SIP_UNSUPPORTED_INIT() macro. For instance,
#define SIPTAG_UNSUPPORTED | ( | x | ) |
Tag list item for pointer to a Unsupported header structure sip_unsupported_t.
The SIPTAG_UNSUPPORTED() macro is used to include a tag item with a pointer to a sip_unsupported_t structure in a tag list.
x | pointer to a sip_unsupported_t structure, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_UNSUPPORTED_REF().
#define SIPTAG_UNSUPPORTED_STR | ( | s | ) |
Tag list item for string with Unsupported header value.
The SIPTAG_UNSUPPORTED_STR() macro is used to include a tag item with a string containing value of a sip_unsupported_t header in a tag list.
s | pointer to a string containing Unsupported header value, or NULL. |
The string in SIPTAG_UNSUPPORTED_STR() can be converted to a sip_unsupported_t header structure by giving the string s has second argument to function sip_unsupported_make().
The corresponding tag taking reference parameter is SIPTAG_UNSUPPORTED_STR_REF().

inline |
Test if header object is instance of sip_unsupported_t.
Check if the header class is an instance of Unsupported header object and return true (nonzero), otherwise return false (zero).
header | pointer to the header structure to be tested |
1 | (true) if the header is an instance of header unsupported |
0 | (false) otherwise |

Copy a list of Unsupported header header structures sip_unsupported_t.
The function sip_unsupported_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next
) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.
home | memory home used to allocate new structure |
hdr | pointer to the header structure to be copied |
When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

inline |
Duplicate a list of Unsupported header header structures sip_unsupported_t.
Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next
) to a list of headers, all the headers in the list are duplicated, too.
home | memory home used to allocate new structure |
hdr | header structure to be duplicated |
When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.
|
inline |
Make a Unsupported header from formatting result.
Make a new sip_unsupported_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_unsupported_t.
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
|
inline |
Initialize a structure sip_unsupported_t.
An sip_unsupported_t structure for Unsupported header can be initialized with the sip_unsupported_init() function/macro. For instance,
|
inline |
Make a Unsupported header structure sip_unsupported_t.
The function sip_unsupported_make() makes a new sip_unsupported_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
home | memory home used to allocate new header structure. |
s | string to be decoded as value of the new header structure |

Header class for Unsupported header.
The header class sip_unsupported_class defines how a SIP Unsupported header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_unsupported_t header structure.
